Orawan's place is conveniently located a stone throw from RCA and ShowDC...the place where I put up my staff to work for next 3 weeks. Orawan's English seemed quite fluent but we switched to Thai. Communication and setup via LINE was fairly straight forward (where she facilitated with her mom/sister since she was out of town).
One quick note, but there's another Lumpini brand condo nearby so make sure you get the right name/direction else taxi driver might take you to another one (which is more known to local taxi).
Price-wise, I find the place to be reasonable and it's a nice bonus to have free access to pool and gym which are quite decent.
In all, won't mind putting up my staff again in future.
